i don’t know what flair i’m supposed to use so please excuse that, but last night i updated my pc and this morning when i went to use it, it asked me to put in the bit locker recovery key. i tried lots of things (not entirely sure what all of them were it’s been two hours straight of attempts, i followed everything everyone said online and my friend was helping me) and i can get into my pc without secure boot, but when i go to turn it on it says “secure boot violation invalid signature detected check secure boot policy in setup” i tried troubleshooting or whatever and it said i couldn’t. i tried uninstalling the update, and it wouldn’t let me.
i don’t know what to do anymore. any advice? please :(
and yes, i DO need secure boot lol i play valorant

so whenever i play any other game it runs just fine (overwatch, fort, genshin, r6) and i play on decent graphics. for some reason, valorant stutters like crazy its unplayable. it didn’t used to, i used to play on max graphics too. i’ve tried updating my drivers, disabling a lottttt of things and enabling them, deleting and reinstalling, capping my fps, and turning my graphics all the way down. yet for some reason its like i skip frames, lag, and micro rubber band? even in the training range. my crosshair will move slightly kind of, or sometimes the game just peeks for me LOL. and no, it is not a mouse issue, and i am not using any third party things.
